What codes to use to zoom in on the camera?

Question

My group is making an app with camera. Only we don’t know what code to use to add zoom into the camera. Does anyone know how to do?

Answer 1

This below will work if the user’s Android is:

• API 8 +

   Camera.Parameters parameters = camera.getParameters();
   int maxZoom = parameters.getMaxZoom(); 
      if (parameters.isZoomSupported()) {
        if (zoom >=0 && zoom < maxZoom) {
         parameters.setZoom(zoom);
      } else {
        // zoom parameter incorreto
      }
     }
